Mean phenotypes from each treatment group during greenhouse growth and production experiment (GP2) with treatments A-E for control, −P control, HA, nHA (15 ppm P), and nHA (56.5 ppm P) respectively (left to right) (A) and comparison of average plants from control treatment A (left), nHA at 56.5 ppm P in treatment E (middle), and +P control plants treated with standard Pi fertilizer (right) (B). Plants shown representing the average phenotype were selected based on height, pod number, remaining leaves, and total number of trifoliate leaves.
